Description
Summary:We reanalyzed the relationship between home range and lizard body size. Our analysis includes home ranges estimated with the convex polygon technique and a recently proposed method for eliminating sample size bias. When analyzed separately, neither insectivorous, carnivorous nor female herbivorous lizards had a significant regression of home range size against body mass; male herbivores had a marginally significant regression. Combining data for the different foraging types resulted in significant regressions for both males and females; the regression for the pooled data set (males plus females) was also significant. Our regression equations differ significantly from previously published equations derived from home range estimates adjusted for sample size bias. Except for the intercepts of the female regressions, our equations do not differ significantly from earlier equations derived from unadjusted home range estimates. Our analysis showed that home range size for the side-blotched lizard, Uta stansburiana, could be accurately determined, without sample size bias, with an average of 13 resightings per lizard.
